Further Investigation into the Performance of Two Different On-Board Emissions Measurement System Compared to Laboratory Measurements 2004-01-3480

This paper is a continuation [1] of the discussion of data collected during an effort in comparing on-board systems (Horiba OBS 1000 and MEMS built by West Virginia University) of Test Cell Equipment during Dynamometer runs (FTP) and on road routes (Sabraton-Bruceton Mills cycle). The OBS data in general, agreed within 6-11% of the lab equipment. In addition, data and installation experience on a heavy duty vehicle, a snow plow, will be presented.
